Turbocharger
Maximum volume

Turbo rpm depend-
ency on speed
Turbo playback frequency depending on engine speed.
Turbocharger

gines acceleration
Playback frequency depends on the difference of set
speed to actual speed (= acceleration).
Turbocharger
Minimum load
Audibility threshold for turbochargers; the load is derived
from CV #367 and #368.
Turbocharger
Frequency increase
Speed of frequency-increase of the turbocharger.
Turbocharger
frequency
lowering
Speed of frequency-decrease of the turbocharger.

Coasting-Key
(or Notching)
for diesel sound pro-
jects
Function key that activates “Coasting“, which forces the
motor sound to a specified speed independent of the driv-
ing situation. Define the (sound) step in CV #375 (often
used for idle sound while coasting).
= 0: does NOT mean F0, but rather that NO key is as-
signed for coasting.
= 1 - 28: One of the function keys F1 - F28 for “Coasting“,
29 = F0
Coasting step
(or Notching)
Motor sound (speed) to be activated with the coasting key
(as per CV #374), independent of the driving situation.
=0: Idle sound (typical coasting situations)
= 1 - 10: Sound step (Diesel engines typically have
5 to 10 notches), which can be activated with the
coasting key (e.g. to represent auxiliary heating at
standstill).
Driving sound
Volume -
(Multiplier)
To reduce the driving sound volume (e.g. Diesel motor with
related sounds such as turbo charger) compared to the
function sounds.
Statistical probability
of switchgear sparks
during
Acceleration
Likelihood for sparks (as per CV #158 Bit 7 for FO7 or
#394 for FO6) when accelerating
= 0: always
= 1: very rarely
= 255: very often (almost always)
Statistical probability
of switchgear sparks

Deceleration
Likelihood for sparks when decelerating (as per CV #158
Bit 7 for FO7 or #394 for FO6)
= 0: always
= 1: very rarely
= 255: very often (almost always)
Manual
electric brake key
key
Defines a function key to manually control the sound of a
“dynamic” or “electric” brake.
Electric brake
minimal speed step
The electric brake shall only be heard between the value
defend in CV #381…
Electric brake
maximum speed
step
…and the value in CV #382
= 0: Pitch independent of speed
= 1 - 255: …depends increasingly on speed.
Electric brake
Deceleration thresh-
old
The number of speed steps to be reduced during deceler-
ation before the electric brake sound is played back.
Electric brake
Driving on slopes
= 0: no effect at “negative” load
= 1 - 255: Sound triggered at “negative” load.
Bit 3 = 0: Sound fades out at the end of the sample
= 1: Sound ends without fading at end
Bit 2 - 0: Prolongation of the minimal runtime of the braking
sound by 0 to 7 seconds, to prevent an interruption in
break sound between speed steps.
Acceleration influ-
ence
on diesel sound
steps
In addition to the selected speed step (defined in the ZSP
flow diagram), actual changes in speed (acceleration, de-
celeration) should also have an influence on the sound due
to the associated increase or decrease in load.
= 0: No influence (sound depends on speed step only)
= 64: experience has shown this to be a practical value
= 255: maximum acceleration response
(highest sound step during acceleration)
Deceleration influ-
ence
On diesel sound
steps
Same as CV #387 but used during decelerations.
= 0: No influence (sound depends on speed step only)
= 64: experience has shown this to be a practical value
= 255: maximum deceleration response
Limited acceleration
influence on diesel
sound steps
This CV determines how far the sound step may deviate
during acceleration from the simple speed step depend-
ence (= difference between target speed from the control-
ler and actual speed).
= 0: No deviation; motor sounds according to
schedule, sound does not depend on acceleration.
= 1 - 254: Dependence increases with value.
= 255: fully dependent on target speed.
Momentum reduc-
tion when driving
solo (engine only)
When switching to solo driving with key defined in CV #347
the momentum reduction is activated (with CV #348, Bit 1):
= 0 or 255: No reduction
= 128: Reduction to 50 %
= 64: Reduction to 25 %
= 1: virtually cancels all momentum.
